Ask HN: NYC tips to reduce burn rate?

I'm currently changing my NYC spending from "comfortable software engineer salary" to "startup founder" to prepare for someday leaving my job and concentrating on a startup. Current plan is to move to decrease rent (maybe go back to having roommates), cook instead of seamless, ride my bike more, and try to decrease my student loan payments.

Anyone have any other ideas or tips? I've been a digital nomad before so I might do that too for a while once I get some traction, but I really like it here in New York for a lot of reasons, the QoL here is just phenomenal, best in the world.
